Yes. However, the filing of the patent application in Canada must be within one year of first public disclosure. To claim priority based on a previously filed United States patent application, the Canadian patent application must be filed within one year of the U.S. filing. Also, a Canadian agent must be designated at the time of filing. The Canadian agent is designated to receive correspondence from the Canadian Intellectual Property Office. The format of the Canadian application is similar to the United States format, so there is usually no changes that have to be made prior to filing.
